HEEL-CUTTING APPARATUS.

To all whom it may concern:

Be it known that I, WiLLIAM J. N sBITT, a citizen of the United States of America, residing at Los Angeles, county of LosAngeles, State of California, have invented a certain new and useful Heel-Cutting Apparatus; and I do hereby declare the following to be a full, clear, and exact description 1 of the invention, such as will enable others 1109137,1109138, and 1109139.

skilled in the art to which it appertains to make and use the same.

' This invention relates to heel cutting apparatus, more particularly to further improvements in the apparatus disclosed in my patents dated Sep. 1, 1914, Nos. 1109136,

The main object of the invention is to provide improvements whereby the construction is simplified and made more compact, practical and commercial, easy and convenient to operate, positive and quick in action; and which improvements cause better working of the apparatus, and enable the operator to do quicker, better, and more accurate work.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a careful consideration of the following description of the preferred ing lever; Fig. 7 is an enlarged plan view of a portion of the apparatus; Fig. 8 is an enlarged plan view of a portion of the apparatus; Fig. 9 is a view like that of Fig. 8,

with some parts broken away and others in changed position; Fig. 10 is a sectional view taken on the line 10'10 of Fig. 8; and Fig. 11 is an enlarged broken sectional view taken on the line 1111 of Fig. 8.

The supporting frame or post 10 has thereon the shelf 11 secured in position by screws 12. A curved arm or extension 13 is providedat the upper part of the post 10 and has mounted thereon the adjustable holder 14 for the shaft 15 on which the Specification of Letters Patent.

pulley 16 isloosely mounted. A band saw 17 passes around the pulley 16 and around the pulley 18 which is arranged fast on the shaft 19 which latter is mounted in the bearing 20 on the post 10. ,Any suitable devlces may be provided to guide and hold the band saw 17 in adjusted position-those indicated at 21 and 22 being of well known construction and therefore needing no description.

The'shelf 11 'has thereon the dove-tail guide 23 on which is mounted the platform 24. Balls 25 arranged in ra'ceways- 26 are interposed between the shelf 11 and the platform 24 to render easy the movement of the platform on the shelf. On the top of the platform 24 is provided a dovetail guide 27 which extends at right angles to the guide 23 and has mounted thereon'the table 28 which is provided with an extension 29 to the underside of which is secured by screws 30 the plate 31 which latter is adapted to make loose contact with the underside of the guide 27 which extends beyond the platform 24.. The table 28 is operated to move it transversely of the platform 24 by means of the lever 32 which is mounted on the pivot 33 on the underside of the plate 31 and has its rearend pivotally mounted on the bracket 34 on the platform 24, and is provided with a handle 35 on its forward end portion. The lever 32 is locked in adjusted position by means of a projection 36 thereon which is adapted to fit in any one of the notches 37 in the arm 38 which is provided with a stop 39 at one end thereof secured-to the platform 24 On the table" 28 is mounted a plate 42 which has the forward end portion thereof,

v mounted on a pivot 43 on the table 28. Posts 44 are provided on the rear end portion of the plate 42, and a hollow lever 45 having. a handle 46 on its forward end has its rear end provided with teeth 47 and mounted on a pivot 48 between the posts 44. A projecting part 49 on the lever 45 is adapted to coact with a projecting part 50' on the plate 42 to clamp the heel of a shoe in position on the plate 42,-and said lever 45 is locked in the clamping position by means of a pawl 51 which is arranged on a pivot 52 between ears 53 on'one of the posts 44 and is adapted to engage the teeth 47 to prevent upward move- "ment of the lever 45. To the pivot 52 is at plate 60 with suitable graduations 61 thereon, and the table 28 has thereon a pointer 62 to indicate the graduations. When the plate 42 is turned on the pivot 43 it is locked in adjusted position by means of the latch 63, which has one end mounted on the pivot 64 on the plate 42, and has on its other end a handle 65 and a projection 66 adapted to fit in any one of the notches 67 in the table 28. A wire 68 is connected to the latch 63 and passes through the opening 69 in the lever 45 and is connected to the finger-lever 70 which latter has one end mounted on the pivot 71 on the handle .46 and has its other end portion passing through the slot 72 in said handle. A stop 78 on the table 28 limits the movement of the plate 42 toward the band saw 17. On the lever 45 is mounted on the pivot 74 the angular bar 75 which is provided with the projection 76 adapted to bear 1 against the forward part of a shoe heel and act as an abutment when the heel is being out by moving it past the band saw 17. A handle 77 on the angular bar 75 is arranged in close proximity to the handle 46 so that both can be operated by the same hand, and a dog 78 which is mounted on a pivot 79 on the angular bar 75 is adapted to engage the teeth 82 on the arm 83 which is secured to the lever 45. A spring 81 on the angular bar 75 is adapted to press the dog 78 into engagement with the teeth 82, and said dog can be moved out of engagement with the teeth 82 by pressing down on the handle on said dog.

A shaft 84 is mounted on the brackets 85 which are suitably secured on the underside of the shelf 11. Between the brackets 85 on the shaft 84 is arranged the sector 86 which extends into the slot 87 in the forward portion of the shelf 11 and is provided with teeth 88 adapted to mesh with teeth 89 on the underside of the platform 24. The shaft 84 can be turned by the handle 90 secured thereto. On the platform 91 at the rear of the post 10 is mounted the motor 92 which has fast on its shaft 93 the spur pinion 94 I which latter meshes with the spur wheel 95 which is mounted fast on the shaft 19.

From the foregoing the manner of use and the advantages of'the improved appa ratus will be readily apparent to those skilled in the art. It will be seen thatwhen the motor 92 is operated to drive the band saw 17, the fiIlgGDlGVGI 57 may be pressed to effect disengagement of the pawl 51 from the teeth 47, whereupon the heel of a shoe to be cut is placed between the projecting parts 49 and 50, and then the lever 45 ismoved down to clamp the heel between said projecting parts. The lever 45 is automatically locked in clamping position by reason of engagement of the pawl 51 with the teeth 47 The handle 7 7 of the angular bar 75 may then be pressed down to cause the projection 76 to engage the forward part of the heel. Engagement of the dog 78 with the teeth 82 on the arm 83 automatically locks the angu-- lar lever 75 against movement. By press-- ing down on the handle 80 the dog 78 can be disengaged from the teeth 82. If a straight out of the heel is to be made the plate 42 is moved to position against the stop 73 to have its side adjacent to the band saw 17 flush with the corresponding side of the table 28, whereupon the lever 32 is operated to move the table 28 transversely away from the band saw 17 until the pointer 62 indicates that one of the graduations 61 which corresponds to the amount it is desired to cut off from the heel. The handle 90 may then be moved upwardly to have the sector 86 operate the platform 24 and thereby effect movement of the table 28 and plate 42 thereon to move the heel past the band saw 17 to have the latter cut away a part of the heel. lVhen it is desired to make an angular cut of the heel the finger lever 70 is operated to eifect disengagement of the latch 63 from the teeth 67, and then the plate 42 is turned. horizontally on the table 28 and thus moved away from the band saw until it makes the desired angle with the band saw, whereupon: the finger lever 70 is released and the latch 63 again engages the teeth 67 and the plate 42 is' thereby automatically locked in adjusted position on the table 28.

The construction which has been particularly illustrated and described admits of changes and modifications, wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of the invention which is defined in the appended claims.-
